Embodiment 1

[0032] Figure 1a It is a schematic flow chart of a banknote identification method provided by Embodiment 1 of the present invention. This method is applicable to judging whether the magnetic characteristics of the banknote to be detected conform to the magnetic characteristics of genuine currency. The method can be implemented by the banknote provided by the embodiment of the present invention The counterfeit authentication device can be implemented by means of software and / or hardware, and can generally be integrated into the terminal device.

[0033] Such as Figure 1a As described above, a banknote authenticating method provided in Embodiment 1 of the present invention includes the following steps:

[0034] S101. Obtain the magnetic value of each sampling point in the magnetic area of ​​the banknote to be detected.

[0035] In this embodiment, the banknotes to be detected can be understood as banknotes waiting for banknote authentication. The magnetic area can be understo...

Embodiment 2

[0054] figure 2 It is a schematic flowchart of a method for authenticating banknotes provided by Embodiment 2 of the present invention. This Embodiment 2 is optimized on the basis of the above-mentioned embodiments. In this embodiment, before the acquisition of the magnetic value of each sampling point in the magnetic region of the banknote to be detected, the optimization includes: acquiring an image of the banknote to be detected; identifying characters and numbers in the image of the banknote to be detected; The position information of the recognized characters and numbers and the mapping relationship between the characters and numbers and the magnetic regions determine the magnetic regions of the banknotes to be detected.

[0055] Further, this embodiment will also confirm whether the number of rows occupied by magnetic dots in the first detection area is smaller than the number of rows occupied by magnetic dots in the second detection area, and further optimization is: i...

Embodiment 3

[0094] Figure 3a It is a schematic flowchart of a method for authenticating banknotes provided by Embodiment 3 of the present invention. Embodiment 3 is optimized on the basis of the above-mentioned embodiments. In this embodiment, if there is at least one column of sampling points in the first detection area and the second detection area, the number of peaks or valleys corresponding to the magnetic value is greater than or equal to the first number Before the threshold, the optimization includes: based on the transport direction of the banknote to be detected, determining the maximum value or minimum value corresponding to the magnetic value of each column of sampling points in the first detection area and the second detection area ;

[0095] The number of the maximum value or the minimum value is counted to obtain the number of peak values ​​or valley values ​​corresponding to the magnetic values ​​of each column of sampling points in the first detection area and the secon...

Abstract

The invention discloses a banknote authenticity identification method, a banknote authenticity identification device, a terminal device and a storage medium. The method includes the following steps that: the magnetic values of sampling points in the magnetic region of a banknote to be detected are acquired; magnetic points of which the magnetic values are within a magnetic range are selected fromthe magnetic region, if the quantity of the magnetic points is greater than or equal to a magnetic point quantity threshold value, whether the number of lines occupied by magnetic points in a first detection region is smaller than the number of lines occupied by magnetic points in a second detection region is determined, symbols in the first detection area are characters, and symbols in the seconddetection are digits; and if the number of the lines occupied by the magnetic points in the first detection region is smaller than the number of the lines occupied by the magnetic points in the second detection region, it is determined that the banknote to be detected has magnetic characteristics of a genuine banknote. With the method adopted, on the basis that magnetic point presence qualitativeanalysis is performed the banknotes to be detected, and the magnetic characteristics of the banknotes to be detected in the magnetic region can be quantitatively detected, and therefore, the accuracyof the authenticity identification of the banknote to be detected is effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of banknote identification, and in particular, to a banknote identification method, device, terminal equipment, and storage medium. Background technique [0002] With the rapid development of science and technology, the technical means of counterfeiting banknotes have also been continuously improved, and the circulation of counterfeit banknotes is inevitable in daily life. Therefore, the counterfeiting of banknotes is becoming more and more important. [0003] Among them, the technical means adopted for counterfeiting banknotes include the detection of the magnetic characteristics of banknotes. At present, the 100-yuan banknotes issued in 2015 in circulation on the market have added magnetic materials to the 100-yuan denomination in the ethnic characters area on the back of the banknotes and adjacent to the ethnic characters area, which constitutes the magnetic authentication featu...
